Metal Inert Gas (MIG) and Metal Active Gas (MAG) …
Metal Inert Gas (MIG) / Metal Active Gas (MAG) welding refers to a group of arc welding processes that use the heat generated by a DC electric arc to fuse the metal in the joint area. A continuous electrode (the wire) is fed by powered feed rolls (wire feeder) into the weld pool.

Gas Metal Arc Welding Basics: Welding Current & …
Welding voltage primarily controls the arc length which is the distance between the molten weld pool and the wire filler metal at the point of melting within the arc. As the voltage is increased, the weld bead will flatten out more and have an increasing width-to-depth ratio.

Welding - Wikipedia
Welding is a fabriion process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
Welding and Joining Process Classifiion - TWI
Although fusion welding is one of the simplest joining techniques, problems likely to occur include porosity in the weld metal, and cracking in either the weld or heat affected zone (HAZ). Porosity is avoided by ensuring adequate shielding of the weld pool and, for materials such as aluminium, the addition of filler wire.
8 Tools for Brazing, Braze Welding & Soldering: …
The heat involved with all other welding processes will boil off the brass alloy of a braze weld, ruining the weld and creating toxic fumes. Why Braze Welding Braze welding is helpful for forging thinner metal, (Expanding to a more thicker cut, but relatively thin).

Spray Arc Welding – A welding process by which molten material is transferred in the form of many small droplets, the diameter of which is less than that of the filler wire. Stabilized Stainless Steel – A high-chromium steel that does not lose its chromium from solid solution by precipitation, because of the addition of elements that have a greater attraction for carbon than does chromium.

Meet the Demanding Requirements of Welding P91 Pipe …
2016/6/9· The heat of the welding process makes the weld deposit and neighboring HAZ brittle when welding P91. Post-weld heat treatment restores toughness to the weld deposit and the HAZ. Because precision and stability in temperature control are extremely important when welding P91 pipe, induction heating is a solution that offers better control and more uniform heating of the part.
Effect of current waveforms on metal transfer in pulsed …
2005/10/31· During gas metal arc welding (GMAW), the electrode wire is melted and liquid droplets are formed at the tip of the electrode. When detached from the electrode, the droplets transfer both mass and heat into the weld pool. This process, referred to as metal transfer
What is MIG/MAG Welding? The Basics and advantages
Direct current is used for MIG/MAG welding. The arc burns between the workpiece and a consumable wire electrode, which is also the source of the necessary filler material and is essentially endless. It is supplied either on a spool or in a drum and is guided to the
